This enables the appearance of the pictures of other cameras to be reduced.
22 Playback Procedure Before operating the unit, check that the internal/external timer recording displays (INT/EXT) have been cleared from the display. (If INT or EXT is displayed, use the TIMER MODE switch to clear it.) rPress the PLAY button. PLAY qSwitch on the power to the unit and TV monitor. wInsert the recorded cassette tape into the unit. eSelect the time mode. TIME MODE Notes on operation 1. Bear in mind the following points when playing back parts of a tape recorded in a time lapse (L18 to 240 hour) mode. •When the tape is played back in the same mode, noise resembling dropouts will appear on the screen: this is not indicative of malfunctioning. •The picture may oscillate in the vertical direction: this is not indicative of malfunctioning. •When a tape is played back in the same time mode, the picture may shake slightly sideways: this is not indicative of malfunctioning. •Turn Quasi-V insertion ON ( ) or OFF () with the FWD ADV button. Dancing can be minimized when a tape is played back in a time lapse (L18 to 240 hour) mode. Moreover, playing back a tape in a system featuring a frame switcher enables the appearance of the pictures of other cameras to be reduced. 2. Bear in mind the following points when playing back parts of a tape recorded in a VHS mode (6 hours). •When a tape is played back in a time lapse mode, slight noise may appear at the top and bottom of the screen: this is not indicative of malfunctioning. 3. When noise has occurred during still-picture playback, press the FWD ADV button to play it out. (It may not always be possible to play out the noise.) 4. Bear in mind that if the power cable is disconnected and then re-connected or if the power has been restored after it has failed when the tape was played with EXT indicated on the display by the TIMER MODE button, the unit will automatically be set from playback to the recording mode. 5. When the PAUSE/STILL button is pressed during playback, the unit is set to the pause mode, and a still picture PLAY button. If the unit is kept in the pause mode for more than 5 minutes, it will be set to the stop mode. 6. If the horizontal AFC on the TV monitor is too long or when a video camera with random interlace scanning has been used, the top area of the TV monitor may be distorted: this is not indicative of malfunctioning. 7. A tape recorded in the 2-hour mode on a different deck can be played back in the 2-hour mode. However, it cannot be played back in time lapse (L18 to 240 hour) mode. •“6H” appears when a tape is played back which was recorded for 6 hours using another VTR. 8. Tapes recorded on this machine cannot be played back other VHS video recorder as they are not compatible. 9. When the power cord has come out of the socket or a power failure has occurred during fast forwarding or rewinding, no operations will be acknowledged for about 30 seconds after the power has been restored: this is to protect the tape. Tracking When noise such as that shown below appears on the playback image in the 6-hour time mode, press the tracking (+ or –) button to minimize the noise. TRACKING / V-LOCK •For the tracking default setting, press the “+” and “–” buttons together (in the 6-hour time mode only). •In the L18 or L24 hour mode, press the “+” or “–” button to adjust the tracking. Vertical Hold Adjustment If the image shakes slightly in the vertical direction during still-picture playback, press the V-LOCK buttons (–, +) to reduce the dancing.

The ACK or NAK response must commence within 20ms. When a new command has been received during the processing of an non-interruptible command, the receive verification code is returned within 20ms, after which the applicable ERROR code is returned, and the processing of the previous command is resumed. When it takes time for execution to be completed, it is to be possible for the next command to be processed (in principle, after the ACK response) without waiting for the completion of the said execution. (This applies only to commands whose processing can be interrupted.) When a command which does not entail a transfer of the deck mode is received, the message of having completed the received command is returned regardless of the deck mode. ■Explanatory description • • • • •
